You probably need your own input and output quick connectors to fit your system, unless you happen to have quick connects like the ones they sent (ive never seen them before). Still it seems to work perfectly. I used this and a small compressor to solve the problem of ever buying those $12 "can of air" ever again for cleaning electronics, or dusting. Now I can pump clean air all day long. Review: Just as described. - Works as described, I had to go buy different size fittings, maybe that was my fault by not understanding the details. But once it arrived, very quickly I may add, I was able to get it mounted and connected and it has been working like it should. ## Features - 1/4" NPT Auto-Drain Piggyback Filter Regulator Lubricator Unit - Operating Pressure: 0-125 PSI - 5 Micron Brass Filter Element, Excellent Filtering Performance, Much Longer Life and Reuse Feasibility - Flow Rate: 18 SCFM (500 L /Minute)@90 psi - Includes Polycarbonate Bowl, 0-150 Gauge & Bracket，a pair of Air Coupler＆ Plug Kit, 2 x 1/4" NPT Fittings, 1 x Thread Seal Tape ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.4 out of 5 stars 237 Reviews | ## Product Details - **Brand:** NANPU - **Item dimensions L x W x H:** 8 x 4.7 x 3.2 inches - **Manufacturer:** NANPU - **Material:** Polycarbonate (PC) - **UPC:** 708257830370 ## Images ![NANPU 1/4" NPT Auto-Drain Air Filter Regulator Lubricator Combo (FRL) Water/Oil Trap Separator - Gauge(0-150 psi), 5 Micron Brass Element, Poly Bowl, Metal Bracket - Image 1](https://m.media-amazon.com/images/I/81Pjf8wkCaL.jpg) ![NANPU 1/4" NPT Auto-Drain Air Filter Regulator Lubricator Combo (FRL) Water/Oil Trap Separator - Gauge(0-150 psi), 5 Micron Brass Element, Poly Bowl, Metal Bracket - Image 2](https://m.media-amazon.com/images/I/81kOE5SMl+L.jpg) ![NANPU 1/4" NPT Auto-Drain Air Filter Regulator Lubricator Combo (FRL) Water/Oil Trap Separator - Gauge(0-150 psi), 5 Micron Brass Element, Poly Bowl, Metal Bracket - Image 3](https://m.media-amazon.com/images/I/815nCYzL5YL.jpg) ![NANPU 1/4" NPT Auto-Drain Air Filter Regulator Lubricator Combo (FRL) Water/Oil Trap Separator - Gauge(0-150 psi), 5 Micron Brass Element, Poly Bowl, Metal Bracket - Image 4](https://m.media-amazon.com/images/I/81PegJjfRIL.jpg) ![NANPU 1/4" NPT Auto-Drain Air Filter Regulator Lubricator Combo (FRL) Water/Oil Trap Separator - Gauge(0-150 psi), 5 Micron Brass Element, Poly Bowl, Metal Bracket - Image 5](https://m.media-amazon.com/images/I/81yZgxw6wSL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great! *by A***D on May 7, 2026* No Instructions, but fairly simple to setup if you know what you are doing.
